Coastal Ecosystems

Overexploitation, use of destructive fishing practices, human development and pollution within coastal areas have degraded and destroyed coastal habitat and caused losses in nearshore biodiversity and fish stock biomass, resulting in a decreased human quality of life.

  • Forty percent of the world's population lives with 100 kilometers of a coastline, an area that accounts for only about 20 percent of the land mass.
  • Population increase and conversion for development, agriculture, and aquaculture are reducing mangroves, coastal wetlands, seagrass areas, and coral reefs at an alarming rate.
  • Fish and shellfish provide about a sixth of the animal protein consumed by people worldwide. A billion people, mostly in developing countries, depend on fish for their prime source of protein.

  • Coastal ecosystems have already lost much of their capacity to produce fish because of overfishing, destructive trawling techniques, and destruction of nursery habitats.

  • Rising pollution levels are associated with increasing use of synthetic chemicals and fertilizers.
